Reduction of Ordered Spin Moments in Antiferromagnets of S = 5/2 Ions (Fe3+, Mn2+) Driven by Local Magnetic Excitation
Myung-Hwan Whangbo, Reinhard K. Kremer, Hyun-Joo Koo
For antiferromagnets composed of spin five-half ions, the moments of these ions in the ordered antiferromagnetic state can be significantly smaller than 5 BM (i.e., 1.56 - 4.48 BM)…

Le Chatelier principle and field-induced change in magnetic entropy leading to spin lattice partitioning and magnetization plateau
Myung-Hwan Whangbo, Hyun-Joo Koo, Olga S. Volkova
For a certain antiferromagnet, the magnetization does not increase gradually with increasing magnetic field but exhibits field region(s) typically at an integer fraction of its sat…

Magnetization Plateaus by the Field-Induced Partitioning of Spin Lattices
Myung-Hwan Whangbo, Hyun-Joo Koo, Reinhard K. Kremer +1
To search for a conceptual picture describing the magnetization plateau phenomenon, we surveyed the crystal structures and the spin lattices of those magnets exhibiting plateaus in…
