Description
We investigate the magnetic fluctuation spectrum of the geometrically frustrated antiferromagnetic compound UNi4B, which partially orders below TN=20 K. An overdamped spin excitation is observed at the AF wave vector around 2.4 meV. Low-frequency, weakly Q-dependent inelastic scattering increases towards lower temperature, hinting at the approach of a newly discovered weak phase transition around 300 mK. (orig.)
