The capacitance of a double-heterojunction structure with a wide GaAs undoped layer embedded between two selectively doped \(\mathrm{AlGaAs}\) barriers is calculated selfconsistently as a function of intensity of the in-plane magnetic field. With increasing field intensity the capacitance initially
By applying pulsed high magnetic fields up to 40 T, we studied magneto-tunneling properties in AIGaAs/GaAs/AIGaAs double-barrier resonant-tunneling devices in a quantum-limit regime. A distinct resonance of tunneling current and a hysteresis of current vs voltage curves which originate from the disc
## Abstract The magnetic orientation of the rodlike bacterial viruses Pf1 and fd in dilute aqueous solution was detected by highβresolution birefringence measurements. Partial alignment takes place parallel to the magnetic field chiefly due to the diagmagnetic anisotropy of the highly ordered Ξ±βhel
