We present a comprehensive experimental and theoretical investigation of the thermodynamic properties: specific heat, magnetization, and thermal expansion in the vicinity of the field-induced quantum critical point (QCP) around the lower critical field Hc1≈2 T in NiCl2-4SC(NH2)2. A T3/2 behavior in...
