Quenching of spin fluctuations in scandium

The low temperature (1.3 to 20 K) heat capacity of electrotransport purified scandium metal was measured in magnetic fields up to ∼10 T. The electronic specific heat constant, γ, decreases with increasing magnetic fields (11% at 10 T), while the coefficient to the T 3 term of the heat capacity, β, rises rapidly with increasing field and becomes almost constant at T > 5 T. The decrease in γ is thought to be due to the depression of spin fluctuation enhancement by the magnetic field. The increase in β is believed to be due to an induced magnetic moment on the scandium atoms caused by the applied magnetic field.
