We present an investigation of the optical constants of the near stoichiometric GdN films. Transmission and reflection spectra are collected for the paramagnetic and the ferromagnetic GdN in the photon energy range of 0.5-5.5 eV. In the ferromagnetic phase, behaviors of minority and majority spin states are specifically focussed on, which indicate spin-split joint density of states. The results confirm the LSDA＋U estimates of energy gap associated with the majority-spins and also the magnitude of spin splitting.

With global improvements in life expectancy,the proportion of the world’s population over 60 years of age has grown by 3%annually,and it is expected that by 2050,this population segment will nearly double.[1]This demographic transition carries profound impact on public health,with far-reaching economic implications for healthcare delivery,social and inhome care.[2]One of the most troublesome health manifestations of an ageing population is frailty,a multidimensional syndrome of accumulated ageand disease-related deficits that results in reduced resilience and increased vulnerability to stressors.
