Magnetic field-induced phase transitions in a weakly coupled s = 1/2 quantum spin dimer system Ba${}_3$Cr${}_2$O${}_8$

M. Kofu, H. Ueda, H. Nojiri +8

By using bulk magnetization, electron spin resonance (ESR), heat capacity, and neutron scattering techniques, we characterize the thermodynamic and quantum phase diagrams of Ba${}_3$…
