AbstractThermally induced decay of longitudinally recorded magnetic transitions is measured on a spin-stand. The decay rate increases with increased linear density and decreases with increased media coercivity. A new spin-stand experimental technique has been developed which allows measurements of the time dependence of the media coercivity as a function of write times spanning short times characteristic of write times in drives to long times associated with VSM measurements. The ratio of long to short write time coercivity was larger for media which are thermally unstable.

Triplet Energy Transfer

A solution of spiroindolinonaphthoxazine in a common organic solvent shows profound photochromic effect. The colorless form in ethanol displays three absorption bands (~320, 235, 203 nm) in the ultraviolet region of the spectrum. The absorption spectrum of the colored metastable form shows two prominent absorption peaks at 612 and 578 nm. The triplet state energy level of the colorless form is estimated to be in the range from 2.4 × 104 to 2.1 × 104 cm−1 by the triplet–triplet energy transfer method. There exists a thermal equilibrium between the colorless and colored forms. From the measurement of absorbance of the colored form at different temperatures, the standard enthalpy of equilibrium is obtained (ΔH0 = 1500 cm−1). The thermal decay of the colored form to the colorless form depends strongly on temperature. The decay rate increases three times for every 10 °C increase in temperature. From these temperature dependence studies of the thermal decay rate, the thermal energy barrier for the colored metastable state to decay to the colorless form is determined to be 6.9 × 103 cm−1.

A new synthetic method was developed to incorporate spiropyran into thiophene based materials via a conjugated pathway. As the number of thiophene units increased, the thermal decay rate of the reverse reaction decreased in methanol, thus increasing the half-life of merocyanine.
