Specific heat of the $S=1$ spin-dimer antiferromagnet Ba${}_3$Mn${}_2$O${}_8$ in high magnetic fields

H. Tsujii, B. Andraka, M. Uchida +2

We have measured the specific heat of the coupled spin-dimer antiferromagnet Ba${}_3$Mn${}_2$O${}_8$ to 50 mK in temperature and to 29 T in the magnetic field. The experiment extends to…
