  EuTiO_3, which is a G-type antiferromagnet below T_N = 5.5 K, has some
fascinating properties at high temperatures, suggesting that macroscopically
hidden dynamically fluctuating weak magnetism exists at high temperatures. This
conjecture is substantiated by magnetic field dependent magnetization
measurements, which exhibit pronounced anomalies below 200 K becoming more
distinctive with increasing magnetic field strength. Additional results from
muon spin rotation (${\mu}$SR) experiments provide evidence for weak
fluctuating bulk magnetism induced by spin-lattice coupling which is strongly
supported in increasing magnetic field.
