      abstract     = {Although the majority of studies on battery materials have
                      focused on enhancing their electrochemical performance, the
                      understanding of their magnetic and atomic structures as
                      well as the intimate connections between these structures
                      and properties is significant. Muon spin relaxation (μSR)
                      spectroscopy and neutron scattering techniques at low
                      temperature have been used to explore the nature of the
                      magnetic state of Li(Ni0.4Mn0.4Co0.2)O2 cathode materials.
                      Interestingly, the μSR experiment reveals that the spins of
                      Ni/Mn/Co ions turn glassy at a low temperature of 19 K,
                      while the unprecedented spin dynamics survives until the
                      base temperature of 5.6 K. Moreover, the complementary
                      neutron scattering measurements show magnetic diffuse
                      scattering signals in the form of a broad peak at
                      Q = 1.6 Å−1 attributed to short-range spin
                      correlation which establishes below ∼120 K. Upon cooling
                      to as low as 480 mK, long-range magnetic order still could
                      not be established. The inelastic neutron scattering
                      intensities demonstrate clearly the existence of dynamic
                      spin fluctuations. In contrast to the conventional spin
                      glass system, the coexistence of both dynamic and static
                      components in the ground state suggests an unconventional
                      spin glass state in magnetically frustrated
                      Li(Ni0.4Mn0.4Co0.2)O2 cathode materials for Li-ion
                      batteries.},
