One class of materials named for this quantity exhibits frustrated magnetism and is exemplified by dysprosium (10[1])titanate. Interactions between two of these quantities are described in the Sherrington–Kirkpatrick model, which models a set of magnetically-disordered materials named for this quantity. (10[1])The Ising (10[1])model of ferromagnetism uses a lattice where each atom is assigned a value of this quantity. (-5[1])This quantity names “ice” and “glass” (10[1])magnetic states (10[1])in condensed matter physics. Silver atoms were fired through a magnetic field to demonstrate this (10[1]-5[1])quantity’s (10[1])quantization (10[2])in (10[1])the (10[1])Stern–Gerlach experiment. Particles that obey the (10[1])Pauli exclusion principle have a half-integer value of this quantity (10[1])and are known as fermions. For 10 points, name this intrinsic angular momentum of a particle. ■END■ (10[1])
