Waea Koranu Aukume Ngāwari Ni77mo4cu5

Whakaahuatanga Poto:

(Koranu aukume ngohengohe)

He koranu aukume nikara-rino te Ni77mo4cu5, me te 80% o te nikara me te 20% o te rino. I hangaia i te tau 1914 e te tohunga ahupūngao a Gustav Elmen i Bell Telephone Laboratories, he mea rongonui mō tōna urunga aukume tino teitei, e whai hua ai hei rauemi matua aukume i roto i ngā taputapu hiko me te hiko, me te ārai aukume hoki hei aukati i ngā papa aukume. Ko ngā koranu permalloy arumoni he tikanga he urunga whanaunga tata ki te 100,000, ki te whakaritea ki ngā mano tini mō te maitai noa.
Haunga te urunga nui, ko ōna āhuatanga aukume ko te iti o te kaha whakakā, te tata kore o te aukume, me te ātete aukume anisotropic nui. He mea nui te iti o te aukume mō ngā tono ahumahi, e āhei ai te whakamahi i roto i ngā kiriata angiangi i te wā e puta ai he rerekētanga nui o ngā āhuatanga aukume nā ngā ahotea rerekē. Ka taea e te ātete hiko o Permalloy te rerekē tae atu ki te 5% i runga i te kaha me te ahunga o te papa aukume kua whakamahia. Ko ngā Permalloy he hanganga karaihe poraka kei waenganui o te mata me te pūmau whatunga tata ki te 0.355 nm i te taha o te kukū nikara o te 80%. Ko te ngoikoretanga o te permalloy ko te kore e tino ngawari, e kore hoki e taea te mahi, nō reira ko ngā tono e hiahia ana ki ngā āhua matatini, pērā i ngā parenga aukume, ka hangaia mai i ētahi atu koranu urunga teitei pērā i te konganuku mu. Ka whakamahia te Permalloy i roto i ngā whakapiringa whakawhiti me ngā pane tuhi aukume.
E whakamahia whānuitia ana te Ni77mo4cu5 i roto i te umanga reo irirangi-hiko, ngā taputapu tika, te mana mamao me te pūnaha whakahaere aunoa.
