Magnetic susceptibility and heat capacity of a novel and also in applied magnetic fields i introduction magnetic susceptibility data are indicative of an. The magnetic susceptibility values of various molecular fragments are called pascal's constants diamagnetic materials, like water, or water-based materials, have a relative magnetic permeability that is less than or equal to 1, and therefore a magnetic susceptibility less than or equal to 0, since susceptibility is defined as χ v = μ v − 1.
