Nanorazmernye Magnito - Elektrouporyadochennye Sistemy: Relaksatsionnye Yavleniya V Nekotorykh Nanorazmernykh Magnitoelektrouporyadochennykh Sistemakh Anastasiya Rodionova Russian edition

K magnitoelektrouporyadochennym sistemam (MEUS) v pervuyu ochered' mozhno otnesti ferromagnetiki, ferrity, segnetoelektriki, segnetomagnetiki, magnitoelektriki, magnitnye zhidkosti i pr. MEUS ispol'zuyutsya v samykh raznoobraznykh ustroystvakh v kachestve elementov nositeley pamyati, datchikov, izmeritel'nykh zondov, magnitostriktorov, p'ezomoduley, mikro- i nanoprivodov i pr. Pri etom MEUS vygodno otlichayutsya ot prochikh sistem unikal'noy vozmozhnost'yu davat' zametnyy otklik na magnitnoe, elektricheskoe pole i mekhanicheskie (uprugie) vozdeystviya, a v segnetomagnitnykh kristallakh ? elektricheskim polem vliyat' na magnitnuyu podsistemu i naoborot. V rabote priveden raschet relaksatsionnykh parametrov na osnove detal'nogo ucheta simmetrii nanorazmernykh kristallicheskikh sistem, opredelyayushchey ikh termodinamicheskiy potentsial s uchetom vsekh vkhodyashchikh v nego podsistem. Pri etom vo vzaimosvyazi uchityvayutsya kak protsessy vrashcheniy v domenakh, tak i smeshcheniy domennykh granits. Na praktike nanorazmernye MEUS mogut byt' vostreb ovany v elektro- i akusto ?optike, nelineynoy optike, v robototekhnike, kvantovoy elektronike, v kachestve nositeley informatsii, v meditsine, biologii i t.d.
