Magnetoresistance of ruthenium in strong magnetic fields
Alekseevskii N.E. , Bertel K.-H. , Nizhankovskii V.I. and Urai L.
The magnetoresistance of single-crystal ruthenium samples with different orientations is investigated in a transverse magnetic field up to 155 kOe. Magnetic breakdown in samples with axes close to the  direction was observed in fields > 90 kOe,
