Overview

What is he best known for?

The fields of study he is best known for:

  • Condensed matter physics
  • Organic chemistry
  • Ion

His primary areas of study are Condensed matter physics, Antiferromagnetism, Magnetic susceptibility, Pyrochlore and Crystallography. His Condensed matter physics research is multidisciplinary, incorporating elements of Neutron diffraction, Neutron scattering and Quantum spin liquid. John E. Greedan interconnects Phase transition, Paramagnetism, Copper oxide and Stoichiometry in the investigation of issues within Antiferromagnetism.

His Magnetic susceptibility research focuses on Magnetic moment and how it relates to Exchange interaction, Curie temperature and Nuclear magnetic resonance. His work deals with themes such as Inorganic compound, Magnetization and Ground state, which intersect with Pyrochlore. John E. Greedan combines subjects such as Stereochemistry and Copper with his study of Crystallography.

His most cited work include:

  • Magnetic Pyrochlore Oxides (733 citations)
  • Geometrically frustrated magnetic materials (608 citations)
  • Cooperative Paramagnetism in the Geometrically Frustrated Pyrochlore Antiferromagnet Tb 2 Ti 2 O 7 (310 citations)

What are the main themes of his work throughout his whole career to date?

John E. Greedan mainly investigates Condensed matter physics, Crystallography, Neutron diffraction, Magnetic susceptibility and Antiferromagnetism. His Condensed matter physics research includes themes of Pyrochlore and Magnetization. His studies in Neutron diffraction integrate themes in fields like Orthorhombic crystal system, Magnetic structure, Rietveld refinement and Magnetic moment.

He has researched Magnetic susceptibility in several fields, including Paramagnetism, Valence, Spinel, Curie–Weiss law and Nuclear magnetic resonance. His Antiferromagnetism study combines topics in areas such as Magnetism, Neutron scattering, Frustration, Ground state and Heat capacity. His work carried out in the field of Spin glass brings together such families of science as Muon spin spectroscopy and Quantum spin liquid.

He most often published in these fields:

  • Condensed matter physics (49.65%)
  • Crystallography (35.53%)
  • Neutron diffraction (30.35%)

What were the highlights of his more recent work (between 2008-2021)?

  • Condensed matter physics (49.65%)
  • Crystallography (35.53%)
  • Neutron diffraction (30.35%)

In recent papers he was focusing on the following fields of study:

Condensed matter physics, Crystallography, Neutron diffraction, Antiferromagnetism and Crystal structure are his primary areas of study. His Condensed matter physics study integrates concerns from other disciplines, such as Heat capacity, Neutron scattering and Ground state. His Neutron diffraction research includes elements of Vacancy defect, Magnetic structure, Spin glass and Muon spin spectroscopy.

His study in Antiferromagnetism is interdisciplinary in nature, drawing from both Magnetization, Frustration, Spin, Magnetic susceptibility and Lattice. The concepts of his Crystal structure study are interwoven with issues in Stoichiometry, Single crystal and Ferrimagnetism. He works mostly in the field of Spin-½, limiting it down to topics relating to Pyrochlore and, in certain cases, Physics beyond the Standard Model and Transition metal, as a part of the same area of interest.

Between 2008 and 2021, his most popular works were:

  • Magnetic Pyrochlore Oxides (733 citations)
  • Magnetic properties of the geometrically frustrated S=(1)/(2) antiferromagnets, La 2 LiMoO 6 and Ba 2 YMoO 6 , with the B-site ordered double perovskite structure: Evidence for a collective spin-singlet ground state (63 citations)
  • Magnetic properties of the S = 3 2 geometrically frustrated double perovskites La 2 LiRuO 6 and Ba 2 YRuO 6 (52 citations)

In his most recent research, the most cited papers focused on:

  • Condensed matter physics
  • Organic chemistry
  • Ion

John E. Greedan mainly focuses on Condensed matter physics, Neutron diffraction, Antiferromagnetism, Crystallography and Brownmillerite. His Condensed matter physics research is multidisciplinary, relying on both Neutron scattering and Ground state. His Neutron diffraction research incorporates elements of Distribution function, Heat capacity and Magnetization.

His Antiferromagnetism research integrates issues from Magnetic structure, Lattice, Diffraction and Magnetic susceptibility. His research integrates issues of Curie constant and Phase in his study of Magnetic susceptibility. A large part of his Crystallography studies is devoted to Crystal structure.
