High sensitivity sensor for moderate pressures

Abstract

The metal-insulator transition of (V_(0.99)Ti_(0.01))_2O_3 is marked by dramatic changes in the electrical resistivity and the magnetic susceptibility, with a linear pressure variation of -6.06 K/kbar for P≤15 kbar. We propose its use as the sensing element of a manometer in applications where the superconducting transition of soft metals has been traditional.
