Abstract

The phase diagram of SrTi

O_{3}

has been measured with uniaxial pressure along [100] in the neighborhood of its bicritical point. The phase boundary line follows a single power law,

T_{c} (p) - T_{c} (0) = {Wp}^{\frac{1}{φ}}

, with the crossover exponent

φ = 1.27 \pm 0.06

. The value of

φ

is in agreement with the theory for a Heisenberg

n = 3

,

d = 3

system.
