Magnetic Entropy in a NonCollinear Weak Ferromagnetic YCrO3
Abstract
We carried out temperature and field dependent magnetic measurements to understand the evolution of magnetic noncollinearity near antiferromagnetic phase in conjunction with the evolution of magnetic entropy near phase transition. We observed the maximum change in entropy just before magnetic ordering of Cr3+ in YCrO3 with the maximum change in magnetic entropy of 0.38 Jkg1K1 at 8 Tesla external field. The data is linear in higher fields 3 T  8 T , whereas it showed deviations in the lower field region. The maximum entropy change fits well with mean field approximation at higher fields, while the observed deviation in lower field substantiates the onset of weak ferromagnetism in YCrO3.
