Physics Articles and Papers
EPR from Gd3+ ions in the high-Tc≃90 K superconductor GdBa2Cu3Ox is reported. The temperature dependence of the linewidth and intensity of the Gd3+ ions in the vicinity of Tc are related to the corresponding characteristics of the Cu2+ ions.

Physics Articles and Papers
We have detected the zero-field electron-spin resonance signal of Al2O3 with ∼1000 ppm Cr3+ using an edge Josephson junction. The sample comprises the substrate upon which the junction was fabricated and the coupling to the electron-spin resonance is via the solitons which exist in these "long" devices.
