To measure full three-dimensional spin wave of BiFeO3 single crystal
Of all multiferroic materials, BiFeO3 stands out particularly with its both magnetic and ferroelectric transition temperatures above room temperatures, and more interestingly... -
Magnetic Excitations in Chromium
Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
magnetic excitation in square lattice 2D heisenberg antiferromagnet Sr3Fe2O6.5
Oxygen doping in Sr3Fe2O7-x is of special interest because it allows us to continuously tunethe magnetic interactions and dimensionality in a strongly correlated system....
