Effect of Pressure on the Superconducting Transition Temperature of Lanthanum

Abstract
The variation of the superconducting transition temperature of hcp lanthanum has been measured as a function of pressure up to 10 kbar. An approximately linear increase of Tc with applied pressure was observed (TcP14×105 °K bar1). The relation of this behavior to two recently proposed theories for the superconductivity of lanthanum is discussed.
