title = "Ferromagnetism of potassium metal under pressure loading into zeolite low-silica X",
abstract = "Potassium metal was loaded into K-form zeolite low-silica X (LSX) under the loading pressure P up to 1.5 GPa. A ferromagnetism is observed at P≈ 0.9 GPa below 13 K. The loading density of K atom n is estimated to be ≈15 per cage at the ferromagnetic loading pressure, and the pressure-derivative loading density dn/dP has a remarkable peak ≈11GPa-1 at P≈0.95 GPa. The density of states at the Fermi energy is estimated to be ≈46 states/eV per cage from the value of dn/dP on a simple model. The observed ferromagnetism is discussed in terms of the Stoner condition and the theory of the revised Rhodes-Wohlfarth plot.",
