Electron spin resonance of Er in cubic metals: Th:Er, Rh:Er, Pt:Er and Cu:Er☆

Abstract The first observation of the electron paramagnetic resonance of Th:Er, Rh:Er, Pt:Er and Cu:Er is reported. A comparison of the exchange interaction between the Er and the conduction electrons in the noble metals Cu, Ag and Au is given.

Electron spin resonance of Er in high susceptibility metals

Abstract The magnetic resonance of Er in dilute Pt and Pd based alloys is reported. Large negative g shifts in both hosts are inferred from the systematics of the hyperfine coupling, and the proportionality of Er and Gd g shifts to the host metal susceptibility of Pt, Pd and Rh alloys.

Paramagnetic resonance of a non S-state localized moment in metal: Ag: Dy

Abstract The first observation of the magnetic resonance of dysprosium in a metal ( Ag : Dy) is reported. The properties of the resonance can be understood in terms of a 4f 9 configuration, Russell-Saunders-Hundrule ground level, in the presence of a cubic crystalline field. A value for the localized-conduction electron exchange coupling J = 0.25 ± 0.1 eV in Ag :Dy is extracted from the temperature dependence of the resonance linewidth.

Hyperfine splitting in the electron spin resonance of Dy and Er in the transition metal-Rh☆

Abstract The first observation of the hyperfine splitting of the Dy localized moment in a metal is reported. The measured shifts for Gd, Dy and Er and the hyperfine constants for Dy and Er in rhodium, are presented and discussed.

Electron spin resonance of Dy and Er in Ir

Abstract The electron spin resonance of Er and Dy in Ir is reported. The exchange interaction between the localized moment and the conduction electrons is separated into f-d and f-s character, and estimates are given for its component magnitudes.
