Numerical interchain mean-field theory for the specific heat of the bimetallic ferromagnetically coupled chain compound MnNi(NO${}_2$)${}_4$(en)${}_2$ (en = ethylenediamine)

Andreas Honecker, Wolfram Brenig, Maheshwor Tiwari +3

We present a detailed study of the field-dependent specific heat of the bimetallic ferromagnetically coupled chain compound MnNi(NO${}_2$)${}_4$(en)${}_2$, en = ethylenediamine. For this…
