- The nonlinear ac susceptibility chi’-nl of the short-range Ising spin glass Fe0.5Mn0.5TiO3 has been measured using a superconducting-quantum-interference-device magnetometer. The spin-glass temperature, T(g), and the critical exponent gamma were estimated from the temperature dependence of the quadratic field term of chi’nl, yielding T(g) = 20.70 and gamma = 4.0. Static-scaling analyses, using different scaling equations, gave similar results. Using gamma and results from previous dynamic-scaling analyses, a number of critical exponents have been obtained through different scaling relations, e.g., delta = 8.4 and nu = 1.7. The results support the existence of a finite-temperature phase transition in a three-dimensional Ising spin glass.

- Both male and female Orchesella cincta (Collembola) were able to discriminate between spermatophores of different origin. Females chose spermatophores deposited by closely related males while males preferentially destroyed spermatophores of other males.
