The Curie temperatures for x = 0.17 and 0.2 are estimated to be 488 K and 476 K, respectively. The FOMT temperatures (T_{t}) from the ferrimagnetic to antiferromagnetic phase are estimated to be 75 K for x = 0.17 and 145 K for x = 0.2, respectively. By applying magnetic fields, T_{t} decreases and the thermal hysteresis becomes large. The results obtained indicate that kinetic arrest effect in Mn_{2-x}Co_{x}Sb arises when T_{t} is lower than about 40 K.}, pages = {43--49}, title = {Mn_{2-x}Co_{x}Sb (x = 0.17, 0.2) の強磁場中磁気特性}, volume = {45}, year = {2012} }
