Magnetic flux quantization in the weak-localization regime of a nonsuperconducting metal

The magnetic flux quantization effect, with period phi sub 0 = hc /2e, is observed with high accuracy in the resistance of a Mg honeycomb network at temp. 50 mK < = T < = 6K. As expected, the phase of the oscillations and the sign of the magnetoresistance are dominated by the spin-orbit intera...

Description
Summary:The magnetic flux quantization effect, with period phi sub 0 = hc /2e, is observed with high accuracy in the resistance of a Mg honeycomb network at temp. 50 mK < = T < = 6K. As expected, the phase of the oscillations and the sign of the magnetoresistance are dominated by the spin-orbit interaction. Results confirm, for a new geometry, the reality of the Bohm--Aharonov effect for a nonsuperconducting metal in the weak-localization regime. 11 ref.--AA
