High-power yttrium-gadolinium garnet ferrite
The invention discloses a high-power yttrium-gadolinium garnet ferrite having the composition chemical formula specifically expressed as Sm[x]Y[3-x-y-2z-p-q-q']Gd[y]Ca[2z+p+q+q']V[z]Ge[p]Sn[q]Ti[q']In[q'']Al[w]Mn[w']Fe[5-z-p-q-q'-q''-w-w'-[delta]]O[12], wherein 0<=x<=0.20, 0<=y<=3.0, 0<=z<=1.3, 0<=p<=0.9, 0<=q<=0.7, 0<=q'<=0.7, 0<=q''<=0.70, 0<=w<=1.3, 0<=w'<=0.10, 0<=delta<=0.8, and delta represents iron deficient quantity. The high-power garnet ferrite material having high spin wave line width [delta]Hk, low ferromagnetic resonance line width [delta]H and high dielectric constant epsilon' can be obtained.
